man leading a group of people in what appears to be a stretching or warm-up routine, possibly related to dance or performance. The man, who is bald and wearing a gray t-shirt and blue jeans, stands in front of a table, demonstrating the stretches. Around him, about eight people sit on the floor, spaced apart, mirroring his movements. They are dressed in casual athletic wear. A long white table sits in front of the group, holding water bottles, containers, and what appears to be scripts or notes. The room is dimly lit, with a black ceiling, and overhead, a complex array of stage lighting fixtures is visible. In the foreground are black chairs, a backpack, and other belongings, suggesting that the group is in a rehearsal or studio space. The floor appears to be gray concrete.
